We're dividing 806129 by 77 
Let's see how many times 77 fits into 806129.

Advancing to step 1:
8 divided by 77 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 77

On to step 2:
If we divide 80 by 77, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 3 after subtracting 77 from 80.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 77

Let's proceed to step 3:
77 can be fit into 36 0 times, resulting in a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 36 to get 36.
Grab the next digit (1) from the dividend, add it to 36, then carry on: 361 / 77

Going ahead to step 4:
361 divided by 77 is 4 with a remainder of 53.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
If we subtract 308 from 361, we get 53.
Bring next digit (2) of the dividend behind the 53 and repeat the process: 532 / 77

Let's proceed to step 5:
When dividing 532 by 77, we get 6 with a remainder of 70.
The next digit of our result is 6. 
Result so far: 1046.0
Subtract 462 from 532 to get 70.
Fetch the next digit (9) from the dividend, attach it to 70 and continue: 709 / 77

Advancing to step 6:
77 can be fit into 709 9 times, resulting in a remainder of 16.
The next digit of our result is 9. 
Result so far: 10469.0
If we take 693 away from 709, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
77 can be fit into 160 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 10469.2
If we subtract 154 from 160, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
The number 77 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 10469.2
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
600 divided by 77 is 7 with a remainder of 61.
The number 7 becomes the next digit in our result. 
Result so far: 10469.207
Deduct 539 from 600 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 10:
610 divided by 77 is 7 with a remainder of 71.
The next digit of our result is 7. 
Result so far: 10469.2077
If we subtract 539 from 610, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

The quotient of the division is 10469.2077, and the remainder is 0.00071.
